Dragon fruit may seem harmless but it has been found to be good for the elderly and pregnant woman, as well as children and the pregnant woman.
The fruit has a powerful antioxidant and anti-inflammatory effect and has been shown to reduce the risk of many types of cancer, heart disease and diabetes.
The fruits are usually eaten as a fruit in salads, with a splash of honey or honey-sweetened juice added.
The researchers from the University of Washington in Seattle and the University at Buffalo in New York analysed the fruits and found that their antioxidants could protect the skin and prevent skin cancer.
Dr Elizabeth Siegel from the Department of Gerontology at the University Health Network in Toronto said that the antioxidants are found in the skin in small amounts, so eating it every day is not enough.
She said that people who consume more than 20g of fruit daily had a 25% lower risk of developing skin cancer than people who ate fewer than 20 grams.
She added that the antioxidant compounds may help protect the human body from free radicals, the damaging molecules in our bodies that damage DNA.
Dr Siegel said the study could have important health benefits for the public.
“We’ve known for a long time that the skin is extremely vulnerable to free radicals because of the way our cells are made,” she said.
“But what we’ve never seen before is that these antioxidants are actually being released into the skin.”
Dr Sauer added that these antioxidant compounds could help protect against some forms of cancer.
“The more you consume the more you’re going to see, and the more antioxidants are in the system, the better off you are,” she explained.
“In fact, people who eat more fruit are actually much less likely to develop skin cancer and they’re also less likely in general to develop chronic disease.”
The researchers found that the researchers had used a different method to collect the data and they were looking for the antioxidant compound in fruit rather than looking for a specific type of fruit.
The research was published in the journal PLOS One.
